Problems solved by technology

So far, PBSs can be realized by natural birefringent crystals or multi-layer artificial anisotropic materials. In this case, in order to obtain a sufficient beam splitting angle, the plate required is relatively thick, which is not conducive to processing.

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] Such as figure 1 Shown is a reflective polarization separator, which is printed on a very thin dielectric substrate 1, in which the upper surface is a resonant unit (metal patch unit structure 3), and the lower surface is a metal backplane 2; the metal backplane 2 It can reduce the transmission of electromagnetic waves and improve its reflection efficiency.

[0021] Such as figure 2 As shown, the resonant unit is an integrated structure formed by two I-shaped vertical arrangements, and the midpoint of the long arm in the middle of the two I-shaped intersects vertically; an XOY coordinate system is defined on the upper surface of the dielectric substrate 1, and all resonant units, The long arms of the I-shape are all parallel / perpendicular to the X-axis / Y-axis; the two long arms llx and ly in the middle of the two I-shape are selected as variable structural pa...

Abstract

The invention discloses a reflection-type polarization separator. The reflection-type polarization separator comprises a medium substrate, wherein the upper surface of the medium substrate is provided with a metal patch unit structure, the lower surface of the medium substrate is provided with a metal back plate, the metal patch unit structure is of an integrated structure formed by arranging two I-shaped elements in a mutually vertical mode, and middle long arms of the two I-shaped elements are crossed vertically. The reflection-type polarization separator has the following advantages that the polarization separator is easy to manufacture and convenient to manufacture in a large scale and is formed in the mode that artificial electromagnetic material basic units are arranged according to a certain rule, and the adopted process is a printed circuit board process; the polarization separator has the advantages of being flexible in design, structure parameters of the basic units are adjusted and accordingly phase delay of waves at different positions can be changed and deflection of different wave directions is achieved.

Description

technical field [0001] The invention relates to a reflective polarization separator, which separates two mutually perpendicular polarized waves and can be applied to the field of microwave devices. Background technique [0002] In the field of microwave and optics, it is a very important technology to separately control the waves of different polarization modes. One such application is the separation of two mutually perpendicularly polarized waves (PBSs). So far, PBSs can be realized by natural birefringent crystals or multilayer artificial anisotropic materials. In this case, in order to obtain a sufficient beam splitting angle, the plate required is relatively thick, which is not conducive to processing. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a reflective polarization separator, which has low loss and is easy to process, and can increase the reliability of polari...
